Fibroademonas are described as benign breast neoplasms that arise from the epithelium and stroma of the terminal-duct lobular unit. They are quite common and are very often found in premenopausal women in their 20–40 years but can be appreciated in women of any age. Most fibroadenomas present as a distinct, painless breast mass that is patient’s self-discovered and are usually <3 cm in size. The tumor may exceed to 5 cm and is labeled as giant fibroadenoma.

The usual clinical course for breast lumps consistent with fibroadenomas on physical examination and imaging is observation. Although benign, giant fibroadenomas are treated with surgical excision due to patient’s discomfort, back pain, progressive growth, and esthetic concerns. It may also be necessary to rule out other forms of malignancy, as both benign and malignant phyllodes tumors can mimic presentation of fibroadenomas.

The standard treatment of giant fibroadenomas is excision, but the extent of surgery is somehow controversial and ranges from excisional biopsy to reduction mammoplasty or even subcutaneous mastectomy. Simple excision is satisfactory for patients with smaller lesions; however, those with larger tumors can be left with a displeasing, loose, and ptotic breast and may require secondary surgery to address these issues.
